To all It'll/0771 it may concern:

Be it known that I, RUDOLPH Counnonn,

citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful improvements in Apparatus for Actuating' Fluid Under Pressure; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtaius to make and use the same, reference being; had to the accompanying drawing-sand to the letters of reference marked thereon, forming part of this specification.

This in vent-ion relates to apparatus foractuai ing fluid under pressure; and it consistsin certain improvements therein, as will be hereinafter fully described, and set forth in the claims.

More particularly, my invention relates to that class of fluid-actuating, devices wherein a motor fluid is used to actuate another fluid by the direct contact of the actuating and actuated iluids, the actuating and actuated fluids having such diilercnt properties, especially as to specific gravity, as to prevent the mixing of the fluids to any great extent. In carrying out my invention I utilize two chamhers, into which the iiuid to be actuated is admitted, and thou subject the fluid to be actuated in one of the chambers to the motor fluid under pressure; then cutoff the supply oi motor tluid, then connect the two chambers, in order that some of the energy remainiuy, in the motor fluid after the stoppage of the supply may be utilized. Preferably my device is arranged to actuate liquids by the action oigascs und r pressure upon the liquids, and when this done and the mechanism arranged as just hcrcinbcfore described the expansive force of the gas is utilized in the second chamber after the supply is cut oli." in other words the mechanism may he said to compound the gas.

vice wherein nectcd and the compound elilcct utilized the Continuing, my invention comprises a deafter the two chambers are consupply may be turned iutothc second chamher in order to increase its efficiency.

My invention further comprises a mechanism whereby the pressure in the'second chamber may be again compounded in the one above the other and with a continuous connection. I have devised certain devices peculiar to this use of the invention, among which may he mentioned the arrangement of pump-chamber, exitmssage, and valve-float for excluding the motor iiuids from the exitpassage.

In the use of this invention for Artesian wells or mines which are numerous in, a certain territory, it is particularly desirable that a number of wellsor mines be operated from the same source of motor-fluid supply, and it therefore becomes advantageous to arrange a valve device at each well ermine. I have devised a valve mechanism for this purpose which actuated by the motor fluid itself. This valve device so controls the supply of motor fluid as to effect the application of the motor fluid to the pump-chambers in the mannerhereinbctorestated. Proferablythis valve device comprises a Valve-motor which is actuated by the motor fluid, the motor fluid for the valve-motor lacing controlled by a valve device contained in the same valvechamoer with the valve device for controlling the fluid for the pumps.

N here wells or mines are in close proximity they may be operated advantageously by grou nrn, several together, all controlled by the same valve mechanism. I have devised a means whereby this manner of coupling up the different wells may he used, if-desired.

Myinvention further comprises an arrange llltlflhOf the device whereby the motor fluid remaining in any chamber after the closing of the supply and the connection between the chambers may be exhausted to an appreciable extent, so that the remainingfltuid-prcssu re opposing the readmission of fluid to be ac mated to the chamber maybe reduced as much as possible, so as to facilitate'the refill: in; of the chaml'icr.

I have shown my invention'iu its preferred form asadaptcd to the raising of liquids from Artcsian wells, as follows:

hereinafter explained. On the valve-stem H there is a rack ii, and intermeshing therephragrn or valve-seat 1" around with there is a gear-pinion h, on the shaft of ch there is an arm it, upon which there 1:. an adjustable weight h (See Figs. 1, 6, and 7.) The object of this device is that when far enough so that tlie'weight 7L2 is raised .1- ma vertical position, and as soon as the weight h passes the perpendicular, it falls rapidly by gravity, thereby completing the traverse oi the valve, and this operation is repeated at out 1 inverse of the valve in its forward and backward traverse.

' In the well or wells I place a series of two or more cylinders I, according to the depth of the well, those cylinders I being connected together by means of pipe-sections J, which, together with the pipe J, extending up out of the well, constitute the conduit through which the fluid is raised out of the well. In Fig. l I show two wells, with three of the cylinders i (designated as I", I, and i in each well, and in Fig. 2 I show four cylinders I, 1 ,1 and I, referring to Fig. 2. These cylinders are each constructed with an ordinary bail check-valve i in the lower end thereof, which at the bottom closes the top of the perforated suction-pipe K, and between the cylinders it closes the tops of the tubes leading" from the cylinder below.

is a diaphragm operating as a valve-seat i, in the center of which is secured a pipe M, which passes up through a diaphragm: near the top of the cylinder, where it communicates with the pipe J, extending from the upper end of the cylinder to the bottom of the next cylinder above. Through the diathe pipe M there are openings i and around the pipe M there is a vertically-sliding float-valve M", which is raised by the fluid passing up andis floated up thereby until the fluid passes V U 2 and o, and as these cylinders and their mech- -anism are all the same further description thereof is unnecessary. The pipes l) and D I connect with pipes 1) D which pass down 'into' the well through the casing-head N thereof and connect with each alternate oylinder in the well. In Fig." 1 the pipe I) D is shown to be connected in well No l with the cylinders I and If and in well No. 2 with the cylinder I only, while the pipe D D is coi'inectcd in well No. 1 with the cylinder 1 and in well No. 2 with the cylinders I and the piston G has moved the valve E In each cylinder, above the check-valve i, there one of the pipes D or.

I, and in the well shown in Fig. 2 the pipes D D connect with the cylinders I and I and the pipes D I) connect with the cylinders 1 and 1 In operation when the pressure of the air from the compressoris exerted through the pipes D I) upon the cylinder connected therewith the suction or exhaustpipe is connected with and acts through the pipes D D upon the cylinders connected therewith to exhaust the air therefrom, and, vice versa, when the pipes D I) operate as exhaustpipcs the pipes D D act as compression-pipes, this change being accomplished by the reversal of the valve E, as hereinafter described. Referring to Fig. 2, it is seen that the cylinders I and I are empty and the cylinder-s1 and 1" full of fluid. Now if exhaust or snetion is applied to the pipes D D and pressure to the pipes D D the cylinder I will be sucked full of fluid, and at the same time the pressure applied to the cylinders I and I, with the suction upon the cylinders I and I, will transfer the contents of the cylinder I to the cylinder I and force the contenisof the cylinder 1 out through the dischai'ge'-pipe J and at the same time again fill the cylinder I, and if the pressure be now transferred to the pipes D D and the suction to the pipe D I) the contents of the cylinder 1 and 1 which were filled by the first operation, will be transferred to cylinders I and I, and so on, alternately filling and discharging the cylinders. This changing: of the pressure from the one pipe D D to the pipe I) D and vice versa, is accomplished by means of the valve mechanism hcroinbeforc described.

lly referring to Fig. 7 it will be observed that the ports of the valve E when in the position shown in Fig. 7 show' the ports 6 c in the valve E as coinciding with the ports (1'1) in the valve-seat l5, connecting the suction or exhaust pipe I) and the pipes I) D through the passage 0 in the valve E, I) D are connected, through the longitudinal while the pipes recess c and the lateral port o therefrom in v the face of the valve It and the port in the valve-scat 13", directly with the compressed-air supply-pipe a, so that the suction or exhaust pipe 0 is directly connected with the exhaust, the pipes 1) D and the cylinders connected therewith, while the-pressure from the compressor A is at the same time exerted directly upon the pipes D .l) and the cylinders connected therewith. Now as the valve IQ is movedtoivard the opposite end of its traverse, when about the middle 'of such traverse the ports c and c therein for a.

and bi short time coincide with the ports Z) in the valve-seat B which-connects the pipes D and D through the port a a sufficient time topermit the pressure in the pipes D D and D D to become equalized, and as the valve Iflcompletes its traverse the ports 6" and e in the valve coincide with'the ports and Win the valve-seat I3 and mnnect thepipes -D' D with the exhaust-pipe Z) through the paslo chamber exhaust-passages for the liquid shall have a considerable area, in order that. l be {low of the liquid may not be restricted by reason of the size of the passage. In the deiice shown I have arranged the flOttt-ELIVG and the haust passage'both within the pump-chamber. This allows a transverse area of the pump-chamber substantially equal to the transverse area of the Well, so that the pumprnay be given substantially a cylindrical shape that is,one possessing the great est strength and at the same time having the greatest possible capacity with the least length. In the application of this invention to the raising of liquids from Artcsian wells I consider this a very important feature.

The valve actuated by the float is preferably one that is seated by movement in the direction of the fluid through the valve-passage to the reduction-tube. This arrangement subjects the valve to the difference in pressure of the fluid in the chamber and that in the educt-ion-tube, so that the fluidpressure is active in effecting, the seating of the valve. I have also placed the checkvalve in within the body of the cylinder and below the level to Winch the liquid rises in said.

cylinder. "Where the pump cylinders are comparatively long, as in Artesian-well prac- 3'0 tice, this does away with the clearance he 4o ply.

tween the bottom of the check-valve and the en trance to the cylinder, so that the incom-' ing liquid is not opposed by a level of liquid reaching to the check-valve m. i It will be noted that the valve mechanism may be arranged directly at the well or any other place where the pump-chainbers are used and that this maybe a considerable distance from the source of motor-fluid sup- It will also'be noted that the valve mechauism,wliich is all contained in the same valve-chest, not only controls the supply of fluid to the pump-chambers, but also the supply of fluid to the valve-motor which notuates the valve. lly-wiredrawingr the supply to the valve-motor any desired frequency can be given to the movements of the valve; This may be accomplished by the valves d cl. Having th us descri bod suitable apparatus and mechanism for the practice of myinven- \tiou, I do not confine myself to the exact mechanism shown and described, as portions thereof may be cinisidcrably modified and changed without departing from the spirit of my invention.
